The DVD with LXF174 had a Linux Mint 15 Mega Mix compilation with three desktops and Unity. I installed it on a spare partition of my hard disk and have tried all desktops. I like KDE the best and have installed many extra KDE packages.

I'd like to now uninstall the other desktops but I'm not sure how to do that safely without affecting KDE. Previous attempts to do a similar operation resulted in disaster and a non-working system.

Can you please tell me the correct procedure? Do I use Synaptic and if so how without affecting KDE?

I used to work in Warrington when I lived in Liverpool (knotty Ash), I worked at Rylands Cables - (drawing steel onto reels - destined to be cut into nails) a bit different from British Insulated Calendar Cables, in Prescott, Lancashire, since I was taught Wire-drawing there extruding Aluminium, Brass, Copper and Cadmium (before they realised it was carcinogenic from the gas the metal gives off)!

I evolved (changed jobs for Plessey (nearer home) PLC on Edge Lane, Liverpool and spent a good while there learning administration and working with BT nine-foot Exchange Carriers using a device at the time called a Strowger (which is why the works was called the Strowger Works). At the time BT was very cagey about their System X which wasn't all that hush-hush in my opinion but kept my mouth shut anyway.
